Network analysis
From Norbury 2021:
Gaussian graphical estimation implemented in the R package qgraph, version 1.6.5 (Epskamp, Cramer, Waldorp, Schmittmann, & Borsboom, 2012). Under this approach, nodes represent observed variables, and connections between nodes (edges) represent unique pairwise associations (partial correlation coefficients), after conditioning on all other variables in the data- set.
